Abstract: It permits tongue-and-groove connection of wooden or similar pieces (18) with a square or rectangular shape in linear or intermeshed composition of the pieces (18). It includes some projections (24) for connection located in two consecutive sides and there exist corresponding recesses (28) on the two sides opposite to the above. Both the projections (24) and the recesses (28) have a configuration in the form of an obtuse angle triangle, adopting an oblique arrangement in order to achieve the intermeshing and having inverted orientations for permitting the coupling between pieces (18) to be able to be done according to a simple diagonal movement of the new piece to lay.   The recesses (28) and projections (24) are located in the lower third of the thickness of the piece (18), the first in a lower flange (29) and the second below a flange (25) of the central third of the thickness of the pieces (18).

Patent CA-2578405-A1 (CA)
Inventor: OZLUTURK FATIH M
IPC: H04B1/707
Filed: 1997-06-23
Abstract: The method involves transmitting a periodic signal from a subscriber unit at an initial predetermined power level. The power level is increased at a predetermined ramp up rate. The periodic signal is detected at a base station when a sufficient power for detection is achieved. A signal from the base station is transmitted which confirms the periodic signal has been detected. The confirmation signal is received at the subscriber unit. The predetermined power level ramp up rate is stopped when the confirmation signal is received. The initial predetermined power level is lower than the power level required for detection by the base station. The power level of the signal is increased at a second predetermined rate which is less than the first rate.

Patent CA-2581006-A1 (CA)
Inventor: GRAWE THOMAS
IPC: C08G18/60
Filed: 2005-10-18
Abstract: An improved aqueous cathodic electrocoating composition that contains an anti-crater agent which is a water-reducible polyester resin having an acid value less than 40 mg KOH/g. The water-reducible polyester is the reaction product of (1) a hydroxy cyclic carbonate; (2) a polycarboxylic acid anhydride; (3) optional monofunctional epoxy resin; (4) a polyfunctional isocyanate resin;  and, (5) a polyamine compound containing tertiary amine and either primary or secondary functionality. The reaction product is neutralized in the presence of acid and water to convert the tertiary amine groups to water-dilutable groups. Hydrolyzable silane groups can also be incorporated into the reaction product to further enhance its crater resistance property. The electrocoat composition produces coatings having a smoother appearance with fewer craters without adversely affecting intercoat adhesion of the cured film to subsequent coating layers applied thereover.

Inventor: WELLER HANS-MICHAEL
IPC: B23B31/20
Filed: 2005-10-12
Abstract: A chuck for accommodating a collet chuck, comprising a housing and a chucking tool seat that is assigned to the housing. The chucking tool seat is embedded in the housing as a separate part via an intermediate filling that is made of polymer concrete for connecting the chucking tool seat and the housing. This design has improved properties regarding damping and the total weight while flat sub-areas that are composed of individual guiding plates can additionally be used as clamping areas of the chucking tool seat. Thus a pyramid-type joint is obtained, which could previously be created with the required precision only by using a lot of effort when producing the same from solid material.

Title: Partial fft processing and demodulation for a system with multiple subcarriers
Inventor: KRISHNAMOORTHI RAGHURAMAN
IPC: H04L27/26
Filed: 2006-03-10
Abstract: Techniques for efficiently performing partial FFT for subcarriers of interest are described. The N total subcarriers may be arranged into M sets. Each set may contain K subcarriers uniformly distributed across the N total subcarriers, where . For the partial FFT, pre-processing is initially performed on time-domain samples to obtain intermediate samples. The pre-processing may include performing M-point FFTs on the time-domain samples and multiplying the FFT outputs with unit complex values. For each set of subcarriers of interest, a K-point FFT is performed on a set of intermediate samples to obtain a set of frequency-domain symbols for that set of subcarriers. Since K is typically much smaller than N, substantial savings in computation and power may be realized when only one or few sets of subcarriers are of interest.
